Engineering Selection Recommendations

Direct Substitutes (Same Tolerance ±1%): FC0402E1000FST1 has no direct substitutes with identical ±1% tolerance in the provided list. All listed alternatives offer tighter tolerance specifications.

Tolerance Upgrade Substitutes (±0.1% Tolerance): FC0402E1000BTBST1, CPF0402B100RE1, ERA-2AEB101X, RG1005P-101-B-T5, RNCF0402BTE100R, and RT0402BRD07100RL provide ±0.1% tolerance with maintained or improved power ratings. These are suitable for applications requiring higher precision. All maintain ROHS3 compliance and MSL 1 rating.

Tolerance Relaxation Substitutes (±0.5% Tolerance): ERA-2AED101X, RG1005P-101-D-T10, RNCF0402DTE100R, and RR0510P-101-D offer ±0.5% tolerance. These are suitable when tolerance requirements are less stringent than the original specification.

Automotive-Qualified Substitutes: ERA-2AEB101X, ERA-2AED101X, RG1005P-101-B-T5, RG1005P-101-D-T10, RNCF0402BTE100R, and RNCF0402DTE100R carry AEC-Q200 automotive qualification. RG series additionally features anti-sulfur protection. These are required for automotive applications.
